BOSTON — Red Sox president of baseball operations Dave Dombrowski was already looking to shore up his beleaguered bullpen when closer Craig Kimbrel was hurt shagging flyballs.
Suddenly, Dombrowski had another big hole to fill.
And he did.
The Red Sox acquired Diamondbacks closer Brad Ziegler early Saturday, hours after learning Kimbrel would likely be sidelined for 3-6 weeks with an injured left knee. He was hurt during BP before Friday's game against the Rays.
"I took a step for a groundball, heard a pop and didn't really think it was anything serious," Kimbrel said Saturday.
Kimbrel is expected to have surgery Monday for a medial meniscus tear.
Kimbrel had been selected for Tuesday's All-Star Game. He was replaced on AL roster by Blue Jays RHP Aaron Sanchez.
Red Sox manager John Farrell said Ziegler will share the closing duties with RHP Koji Uehara, who got the save Friday despite allowing a solo homer to Evan Longoria.
"It's something we've been looking to do, try to add to our bullpen for an extended period," Dombrowski said. "We went back and forth numerous times, then finally agreed to the deal, really right toward the end of (our) game, during the game."
Kimbrel, acquired from the Padres in the offseason for a package of top prospects, has a career-worst 3.55 ERA and 17 saves in 19 chances.
"I think that's the one thing Dave has proven over the course of his career, the proactive-ness or recognizing what our current needs are and being able to anticipate what we'll need when we go forward," Farrell said.
Boston acquired Ziegler for minor-league RHP Jose Almonte and INF Luis Alejandro Basabe. Ziegler, 36, had a 2.82 ERA and 18 saves in 20 opportunities for the Diamondbacks.
Uehara has a 4.96 ERA and three saves and has allowed eight homers in just 322/3 innings.
ALL-STAR GAME: Mets RHP Noah Syndergaard and OF Yoenis Cespedes and Cubs OF Dexter Fowler withdrew from Tuesday's game. They were replaced by Padres LHP Drew Pomeranz, Pirates OF Starling Marte and Reds OF Jay Bruce.
BEE DELAY: A swarm of bees delayed the start of the Brewers' home game against the Cardinals for 10 minutes. The insects were huddled on a fence beside the field, not far from some spectator seating.
BLUE JAYS: OF Jose Bautista, who hasn't played since June 16 because of a hyperextended left big toe, has begun hitting off a tee, manager John Gibbons said. There is no timetable for his return.
BRAVES: C Tyler Flowers left with a left hand injury in the second inning and won't play today.
WHITE SOX: A bizarre dugout injury landed LHP Carlos Rodon on the 15-day disabled list. Making his way onto the field for the national anthem before Friday night's game, Rodon stumbled on the dugout steps and sprained his left wrist while bracing his fall. "I was a little embarrassed. I was like, 'I hope no one saw that,' " Rodon said. "I got out there and was like just laughing when the anthem was going on. I came back in and sat down and I was like, 'Uh, all right, this kind of hurts a little bit.' "
YANKEES: Rookie RHP Chad Green was optioned to Triple-A Scranton/Wilkes-Barre a day after he allowed four home runs against the Indians. RHP Nick Goody was recalled from Triple A.
